So my answer is option c and I
have provided the solution above. If you like my solution and think
that I could help you a bit please give me a thumb up. Thank you in
advance.
11. How much energy from the Sun would the Curiosity Rover collect at Mars' average distance...
The semimajor axis of Mars orbit is about 1.52 astronomical units (au), where an au is the Earth's average distance from the Sun, meaning the semimajor axis of Earth's orbit is 1 au. To go from Earth to Mars and use the least energy from rocket fuel, the orbit has a semimajor axis of 1.26 au and an eccentricity of about 0.21. Starting at Earth's orbit, to follow this path we give the spacecraft an orbital velocity of 40 km/s. ...
I can see here that for question B Stefan–Boltzmann law was
used. However, the energy per unit area is being divided per 4.
why?
